灌胶机胶水拉丝的原因有哪些?
1、开胶延迟
1. Opening delay
在翻开胶头时,由于胶头出胶口与胶阀之间有段间隔,这段之间没有胶水,假如翻开胶头输出口后,立刻开端运动,会招致轨迹开端一小段缺胶。为避免这种状况,在开胶后,延迟一段时间,等候胶水流出,再执行后续的运动。这段延迟时间称为开胶延迟。
When opening the rubber head, there is no glue between the rubber head outlet and the rubber valve because of the interval between the rubber head outlet and the rubber valve. If the rubber head outlet is opened, it will start to move immediately, which will cause a small gap at the beginning of the trajectory. To avoid this situation, after opening the glue, delay for a period of time, wait for the glue to flow out, and then carry out the follow-up movement. This delay time is called the opening delay.
2、关胶延迟
2. Delay of glue shutdown
在关闭胶头后,胶头出胶口与胶阀之间还有胶水未流完,假如在关闭胶头后立刻运动,可能构成胶水拖尾现象。为避免发作,在关闭胶头后,延迟一段时间等候胶水流完,再执行后续动作。这段延迟时间称为关胶延迟。
After closing the rubber head, there is still unfinished glue between the rubber head outlet and the rubber valve. If the rubber head moves immediately after closing, it may constitute the phenomenon of glue tailing. In order to avoid seizures, after closing the rubber head, delay for a period of time until the glue water is finished, and then perform the follow-up action. This delay time is called shutdown delay.
3、拉丝高度
3. Drawing Height
由于某些胶水的黏度较大,在匀速迟缓上抬一段间隔才干将胶丝拉断,不影响涂胶轨迹,这段间隔称为拉丝高度。
Because of the high viscosity of some glue, it is only by raising a interval at a constant speed and slowly that the glue can be broken without affecting the glue trajectory. This interval is called the drawing height.
4、上抬高度
4. Uplift Height
当一段轨迹点胶完毕后,空移下一段轨迹的起点时,为了避免胶头撞针,在完毕点将胶头上抬一段高度保证胶头平安不撞针,再空移下一段轨迹的起始点,这段高度称为上抬高度。
When a trajectory has been glued and empty moved to the starting point of the next trajectory, in order to avoid collision of the glue head with the needle, the glue head is raised to a height at the end to ensure that the glue head does not collide with the needle safely, and then moved to the starting point of the next trajectory empty. This height is called lifting height.
5、提早关胶
5. Turn off glue early
即提早关胶间隔,是指在连续轨迹涂胶中,在抵达终点之前先关闭胶头,以余压和余胶走完后一段轨迹,防止完毕段堆胶。这段轨迹的长度即“关胶间隔”。
That is to say, early shut-off interval refers to closing the rubber head before reaching the end point in continuous trajectory gluing, so as to prevent the glue stacking after the trajectory is finished with residual pressure and residual glue. The length of this trajectory is the "glue closing interval".
6、完毕动作
6. Finish Action
在整个示教轨迹点胶完毕后,为了便当取放工件、进步加工效率或者消弭加工误差,用户能够设定胶头挪动规范位置,或加工文件起点,或加工档完毕点,或复位,或停止档衔接。这个工程称为完毕动作。
After gluing the whole teaching trajectory, in order to take and place the workpiece conveniently, improve the processing efficiency or eliminate the processing error, the user can set the glue head to move to the standard position, or the starting point of the processing document, or the finishing point of the processing file, or reset, or stop the connection of the files. This project is called completion action.
7、斜拉上抬
7. Cable-Stayed Uplift
由于胶水黏度,在关胶后直接停止拉丝动作不能到达拉断胶丝效果,或者拉出的胶丝外形不契合请求。因而在关闭胶头后,执行斜拉上抬动作为拉丝做准备
Because of the glue viscosity, the effect of breaking the filament can not be achieved by stopping drawing directly after closing the glue, or the shape of the pulled filament does not meet the requirements. Therefore, after closing the rubber head, perform the pull-up action to prepare for wire drawing.
8、胶水加热
8. Glue heating
能够试着将胶水加热到一个合适的温度,增加的胶水的活动性,也可从某种意义上处理拉丝!留意加热的温度不可过高!
Can try to heat glue to a suitable temperature, increase the activity of glue, can also handle wire drawing in a sense! Note that the heating temperature should not be too high!
